[PATCH] PPC64 PCI Hotplug/DLPAR Drivers for RPA

From: johnrose
Date: Tue Feb 10 2004 - 17:25:52 EST


Please condider the following patch for inclusion. This patch contains
implementations of the PCI Hotplug and I/O Slot DLPAR Drivers for PPC64 RISC
Platform Architecture. The patch is made against kernel version 2.6.3-rc2.

The PCI Hotplug module allows the runtime addition/removal of I/O adapters on
a PPC64 machine. Due to firmware restrictions, hotplug operations must be
initiated by userspace tools. These operations are initiated using interface
files located at:
/sys/bus/pci/pci_hotplug_slots/<bus_name>
Development contact for this module is Linda Xie (lxie@xxxxxxxxxx).

The Dynamic Logical Partitioning Module allows the runtime movement of
I/O Slots between logical partitions. An administrator can logically
add/remove PCI Buses to/from a PPC64 partition at runtime. These
operations are initiated using interface files located at:
/sys/bus/pci/pci_hotplug_slots/control/
Development contact for this module is John Rose (johnrose@xxxxxxxxxxxxxx).

Due to the size of the patch (~1730 LOC), I have posted it at:

Thanks-
